<p>A method and apparatus for separating adhered paper from paper-covered gypsu m board, involving passing the gypsum board past a magnet (16) to automaticall y remove ferrous materials from the gypsum board without stopping the process/apparatus, pulverizing (18) that gypsum board into a screenable mixture of pieces of paper and smaller separated gypsum board particles, and then screening (20) that mixture and segregating the pieces of paper from th e gypsum board particles. This method and apparatus may optionally also includ e an area for manually pre-sorting and removing non-gypsum materials from the gypsum board prior to pulverization, may optionally also include additional screening steps, and may optionally also include passing the screened and segregated gypsum board particles past a second magnet. The magnets may have self-cleaning belts.</p> |
